Description
- This invention relates generally to the field of ballasts used for fluorescent lamp fixtures and, more particularly, to a leadless ballast housing and mounting bracket assembly for use with OEM or after market fluorescent lamp fixtures.
- A conventional fluorescent lighting fixture includes a ballast to provide the relatively high input voltage necessary to create a voltage potential across a fluorescent lamp to energize the gas resulting in light. The ballast is secured to a lighting fixture, and the high and low sides of the ballast are wired directly into the circuit of the lighting fixture.
- Fluorescent light ballasts are quite old in the art and have become standardized in their shape and enclosure size, wherein the ballast housing constructed from two sheet-metal pieces. One of the sheet-metal pieces is die-cut and bent to provide two generally vertical side faces, a base wall, and transitional angled faces between the base and the vertical side faces. The first pieces is fitted within a second piece which forms a cover for the housing.
- The prevailing standard in the fluorescent lighting industry has been to provide electrical leads which extend through each end wall of the ballast housing, respectively. Some of the leads connect with a lamp socket, and others are coupled with the input power leads.
- Fluorescent light ballasts must be periodically replaced because they have become burned out or are otherwise defective. For industry-standard ballasts, this process can be quite labor intensive. The old ballast must first be detached from the lamp fixture (usually mounted on a ceiling) by removal of the screws in the mounting plate. This action requires that the relatively heavy ballast be held in place on the ceiling over the head of the installer until all screws are removed. Installation of the new ballast requires that the insulation be stripped from the ends of the fixture leads and the ballast leads. Each of the ends to be connected are twisted together, and a plastic threaded nut is then threaded over the twisted conductors. The installation of the ballast can create a hazardous situation for the installer because some of the wires extending from the can be become activated or “live” during the installation process. The presence of live wires can result in an electrical shock, or even electrocution, of the installer.
- There are clear disadvantages to the above-described system of fluorescent ballast installation, however this arrangement has remained the prevailing standard for equipment in the industry, irrespective of other possibly more practical arrangements which have been disclosed in the prior art. A drawback of many of the ballast systems seen in the prior art is that they do not fit the footprint of standard ballast installations and could not be used as a retrofit for existing fixtures.
- Representative examples in the prior art include U.S. Pat. Nos. 5,691,878, and 6,102,550. Van Wagener et al., U.S. Pat. No. 5,260,878, discloses a leadless ballast for an fluorescent light fixture which would fit standard installations, however a drawback of this design is that is still requires the installer to unscrew the ballast from the ceiling. Another disadvantage is that the jack containing the fluorescent light electrical leads must be manually unplugged from the ballast, which could result in a hazardous situation as live wires could become dislodged from the jack during handling.
- There remains long felt need for a fluorescent ballast system which provides for safe, rapid and easy installation of a fluorescent ballast, which at the same time effectively dovetails with present standards of ballast construction, so as to overcome industry resistance to an improved ballast system.
- It is an objective of the invention to provide improved leadless ballast and mounting assembly in which the fixture wires are permanently dressed, thereby obviating the need to handle the wires in the installation process.
- It is another objective to provide an improved leadless ballast and mounting assembly which does not require the use of tools for replacement of the ballast.
- It is still another objective to provide an improved leadless ballast and mounting assembly which fits the footprint of standard ballasts.
- It is a further objective of the invention to provide an improved leadless ballast and mounting assembly which can be utilized in existing fluorescent fixtures without modification of the fixture.
- It is yet a further objective of the invention to provide an improved leadless ballast and mounting assembly which provides a degree of safety and ease of installation not seen in the prior art ballasts.
- In accordance with the above objectives, a leadless ballast and a mounting assembly therefor is provided for a ballast driven fluorescent light fixture having a plurality of electrical leads coupled to at least one lamp socket and a power source comprising a ballast housing having a length and a width, and including a top face, a bottom face, left and right side faces, and first and second end faces. The first end face has a plurality of male electrical connectors extending outwardly therefrom with the electrical connectors being electrically coupled to a conventional ballast component within the ballast housing. The ballast housing is receive in a mounting bracket configured for complementary engagement with the ballast housing. The mounting bracket has a base and a means for attaching the base to a fixed structure, such as a ceiling. The attachment means can be threaded screws insertable through apertures in the base into the fixed structure. The mounting bracket has a width and length approximately equal to the length and width of the ballast housing. The mounting bracket includes left and right side walls and a front wall which are contiguous and normal to the base. The front wall includes a plurality of female sockets adapted for mated engagement with the male connectors which terminate in jacks extending through the front walls. The jacks are adapted to receive a plurality of electrical leads from the fluorescent fixture.
- In another embodiment, the left and right side walls of the mounting receptacle each have at least one angled panel thereto configured for coextensive alignment with the left and right angled faces on the ballast housing, whereby the ballast housing can be inserted into the mounting bracket with the top face adjacent to the fixed structure and maintained in the mounting bracket by the angled panels.
- In another embodiment, the left and right faces of the ballast housing include a plurality of tab structures protruding laterally therefrom, and the left and right side walls of the bracket include a plurality of slots configured for engagement with the plurality of tab structures.
- In yet another embodiment, the mounting bracket can include left and right side walls which have a height somewhat greater than the left and right lips of the ballast housing, and the left and right side walls respectively terminate in a downwardly-angled flanges configured to engage with the left and right lips of the ballast housing to provide snap-in installation.
- In another alternative embodiment, an adapter kit for a conventional fluorescent light ballast is provided which comprises a cap structure configured for mated sliding engagement to a first end of the ballast housing. The cap structure includes an end wall having a perimeter substantially identical in configuration to the perimeter ballast housing. The cap structure further includes an attachment rim extending perpendicularly from the perimeter of the end wall. The attachment rim has a top face, a bottom face, left and right side faces, and angled transition faces between the bottom face and the left and right side faces respectively with the top face being adapted for attachment to the mounting plate of the ballast housing. The end wall has an electrical connector assembly extending therethrough which includes a plurality of jacks accessible from the inside surface of the end wall wherein the jacks are adapted to be coupled to the electrical leads of the ballast and terminating in a plurality of male electrical connectors extending laterally from the outside surface of the end wall.
